But his pals said ‘they don’t trust her.’

Elon Musk’s massive $15 billion fortune might have Amber Heard seeing stars, but the 31-year-old actress, who is currently filming Aquaman in Australia, was brought back down to Earth when the tech entrepreneur, 45, flew his sons — twins Griffin and Xavier and triplets Damian, Saxon and Kai — to Sydney last month.

While Amber captioned a photo of her getting a piggyback from one of Elon’s children with “kidding around,” sources say the Tesla Motors CEO certainly isn’t. “Elon is very serious about Amber. A few of his friends have said they don’t trust her, but Elon won’t listen to a word of it,” reveals the insider. “He’s already mapped out their entire future together.”

Or as Amber’s dad, David, put it: “They want to… settle down and have a family. They are making plans for that.” Ain’t rocket science!
